That's exactly it.  I really appreciate everyone who pointed that out. 
The example in the documentation does exactly that, I simply didn't 
understand its significance.  Thanks.

I took your advice here, too.  It really only saved one line of string

with '#', but at least the submit() function is clearer.  Plus I 
understand the "#tree" thing a little better, which is good. :)
